This implies that the particular URL does not receive any followable links from within the site itself; it only garners nofollow links.
Why is this important?
Using nofollow on internal links communicates to web crawlers that they should not pursue the connected URL. Consequently, the URL will not benefit from the transference of link equity, such as Google's PageRank from the linking page.
This results in a situation where if a URL is only linked internally via nofollow links, it will fail to accumulate the necessary link equity to bolster its ranking potential in search results.
There are instances where it's completely justified for a URL to be linked internally only with nofollow links, such as a privacy or login page. Loud Interactive wants you to be aware of their presence, but not every such instance may be cause for alarm.
What does the Optimization check?
Loud Interactive's hint is activated for any internal URLs that receive nofollow links but lack followed links from other pages within the site.
Examples that trigger this Optimization
This Optimization is triggered for any internal URL detected by Loud Interactive's crawling tools, which does not have any followed internal links pointing to it but has one or more nofollow links.
Why is this Optimization marked 'Insight'?
The 'Insight' label on this Optimization indicates that it may not need immediate action. It's meant to showcase a noteworthy element rather than highlight an error that requires rectification. URLs not intended to be ranked or crawled by search engines are commonplace.
However, verifying that there are no internally linked URLs that you desire to be indexed and crawled is advisable. Should there be such URLs, the appropriate step is to assess their position in the site architecture and ensure they are linked with followed links.
